Modeling and Simulation of Proton Exchange Membrane Fuel Cell Systems

In the domain of proton exchange membrane fuel cell system modeling and simulation, we employ MATLAB's Simulink environment to construct modular system architectures. This approach enables detailed analysis of PEM fuel cell performance characteristics through block diagram implementations, where key components like fuel cell stacks, hydrogen supply systems, and thermal management modules are represented as interconnected subsystems. Through systematic model development and simulation workflows, we investigate parameter impacts on system performance using variable tuning blocks and sensitivity analysis tools. The simulation framework incorporates electrochemical reaction algorithms, mass balance equations, and voltage-current characteristic curves implemented through custom MATLAB functions and Simscape electrical components. This modeling methodology facilitates design optimization for enhanced efficiency and stability, providing valuable references and guidance for advancing proton exchange membrane fuel cell technology through computational analysis and virtual prototyping capabilities.
